Mikhail Antonov commented on HBASE-10569:
-----------------------------------------
Regarding some discussion about hosting META on master
- if we want to run cluster with 1M or 50M regions (HBASE-11165), we may
(will?) have to host META regions on multiple servers
- on the zk-less assignments (HBASE-11059), short-circuit atomic updates of
meta were mentioned (making use of the fact that meta is local to master).
That said, how do we now define that - is hosting meta on master the
very-nice-to-have optimization, or is that pre-requisite for cluster to
function?

> I was thinking simplifying/improving the region assignments. The first step
> is to co-locate the meta and the master as many people agreed on HBASE-5487.
